 processing circuitry configured to
 acquire a timer value for a user relating to interference cancellation, the timer value being set for a timer to be used for measurement reporting; and 
 notify the user of the timer value, wherein 
 
 the user performs measurement reporting with respect to a serving cell in accordance with the timer value, 
 the timer value is greater when the serving cell is a small cell than when the serving cell is a macrocell, and 
 the timer value is a value corresponding to a type of the cell, wherein 
 the timer value corresponds to an offset for the user relating to interference cancellation, the offset being included in a condition for an event that triggers measurement reporting, and 
 the processing circuitry determines whether to perform inter-cell interference coordination for the user on the basis of the offset. 
 
     
     
       14. The device according to  claim 13 , wherein the offset includes an offset for the serving cell of the user and an offset for a neighboring cell.
